Hw-416-b Pir Sensor Datasheet May 2026

He flipped the board over to see the two orange potentiometers. The Time Pot:

The is a compact Passive Infrared (PIR) motion sensor module, commonly used in DIY electronics projects for detecting human movement. It is essentially a variation of the popular AM312 or HC-SR501 sensors, designed for low-power consumption and a smaller physical footprint. Core Specifications Operating Voltage: 2.7V to 12V DC. Static Power Consumption: (ideal for battery-powered devices). Output Signal: High/Low (3.3V High, 0V Low). hw-416-b pir sensor datasheet
